Definitions

  • valves The purpose of such valves is to keep the pressure at the nozzle of an oil-heated system at a constant level that, as far as possible, is adjustable. This is done by returning part of the oil delivered by the pump to the pump intake side or to the oil container by way of a return orifice which is opened to a varying extent depending upon the pressure conditions. Furthermore, the valve performs the function of keeping'a valve, disposed in the nozzle supply line, firmly closed when the oil is not under a sufficiently high pressure, and in particular of closing this latter valve as abruptly as possible when, upon the pump being switched off, the pressure drops below a predetermined minimum level.
  • FIG. 4 is a partial view of the valve, in enlarged scale, in the position shown in FIG. 2.
